Wood Postcard to Seattle

The listing

In the 1930s-50s Grison's Chicken House restaurant in San Francisco had these menus/postcards made of wood. This one is in exceptionally good condition. The back shows it was used, has a 3 cent stamp from 1943 that says Win the War. Sent to someone in Seattle. Measures 6-1/4" x 4-1/4". Really cool old piece of history/nostalgia.
